He is part of a competitive group of centre-back at the bet365 Stadium along with new signings Kevin Wimmer, Bruno Martins Indi and loan addition Kurt Zouma.

Stoke chief executive Tony Scholes said: "It has been a busy summer for us in the transfer market, and we're delighted with the signings we've made. The renewal of Ryan's contract, however, is as significant as any new signing we have made.

"It's unusual in this day and age for a player to spend so long at one club. Ryan has become synonymous with the progress the club has made over the past decade and we're delighted he has committed to at least another four years with us."
